Hot spring

Akagi Onsen Village, which is historic and also called a “medicinal bath,” is located south of Mt. Akagi. It is a natural strong carbonated hot spring that is good for neuralgia, muscle pain, joint pain, stiff shoulders, and poor circulation. It also has rejuvenating and immune effects, and thus it is considered very effective for health promotion.

According to the description on “Yakushizon stone statue,” the guardian Buddha of Akagi Onsen, the hot spring was opened in 1467. Ancient writings note that “Sakai Utanokami, Feudal Lord of Maebashi, had a bath hut built to help people in 1689.” 

There are five small inns in Akagi Onsen Village, which consists of Akagi Onsen, Chuji Onsen, and Takizawa Onsen. In those small inns surrounded by mountains, you can enjoy seasonal landscape and changes embraced by the great nature of Mt. Akagi.


You can fully enjoy beautiful landscapes each season: cherry blossoms at the foot of the mountain and large gregarious azaleas in the spring; mountains covered with green and the beautiful contrast with the blue sky in the summer; the whole mountain covered with colorful autumn colors in the fall—yellow, orange, red, brown, and green of evergreen trees; and the beautiful snowscape in the winter, particularly in Lake Onuma and Kakumanbuchi Marsh around the summit whose mountains and lakes are blanketed in snow and ice.


At the foot of Mt. Akagi, you can enjoy picking fruit, eating soba noodles, and more, all from the varied climate and nutrition in the rich soil. In the farmers’ market at the foot of the mountain, you can find many kinds of vegetables and fruits grown in the fertile soil.
